A single transradial guiding catheter for right and left coronary angiography and intervention.

Aims: There is no data about the utilisation of a single guiding catheter for current routine, transradial, right and left coronary diagnosis and intervention. We investigated the feasibility and safety of using 6Fr, Ikari left (IL) 3.5 guiding catheter for this purpose. Methods and results: This prospective single-centre study enrolled 621 consecutive patients referred for transradial coronary angiography with ad hoc coronary intervention. The radial artery was successfully accessed in 96.8% of patients. Right and left coronaries were successfully engaged in 98.1% of cases. Engagement with good back-up at right and left coronaries (device success) was achieved in 96.6% of cases. Coronary intervention was performed in 61.2% of the cases, among them, 84.5% had coronary stenting. Procedure success was 98.2%. Procedure time was 21.4±15.1 and 65.4±36.1 minutes; mean fluoroscopy time was 6.8±7.2 and 24.1±18.9 minutes and mean contrast volume was 96.2±45.3 and 197.9±46.2 ml for diagnostic and interventional cases respectively. One patient (0.16%) had catheter related radial artery spasm and three patients (0.48%) encountered a catheter induced RCA dissection. Conclusions: Right and left coronary angiography and intervention is feasible and highly successful using IL 3.5 as a single transradial guiding catheter.
